A number of new ROSAT PSPC datasets are available from the HEASARC Calibration
database (ie via anonymous ftp from heasarc.gsfc.nasa.gov). The datasets
are located in the directory:
/caldb/data/rosat/pspc/bcf/sass_ct
and have the names/descriptions as follows:
adc_bins.fits - PSPC ADC non-linearity correction
alkhist_v1_b.fits - PSPCB Gain hist from Prescott fits to Al-K obs (v1.0)
alkhist_v1_c.fits - PSPCC Gain hist from Prescott fits to Al-K obs (v1.0)
gain_kor3_b.fits - PSPCB Spatial Gain Correction: Pos-dep terms (v1.0)
gain_kor3_c.fits - PSPCC Spatial Gain Correction: Pos-dep terms (v1.0)
gnampl_new.fits - PSPC Spatial Gain Correction: Energy-dep term (v1.0)
scal3.fits - PSPC Window Correction: Energy-dep correction term
tabx_093_b.fits - PSPCB Window Correction: X-axis term
tabx_093_c.fits - PSPCC Window Correction: X-axis term
taby_093_b.fits - PSPCB Window Correction: Y-axis term
taby_093_c.fits - PSPCC Window Correction: Y-axis term
These datasets should be marked good in all CIFs. Further instructions on
their use will be supplied to users by the ROSAT GOF at NASA/GSFC in the
near future, but Local Caldb Managers are warned that these datasets will
be required for the task ftools/rosat/pcpicor scheduled for release with
ftools v3.4 in the next few days.
